Abstract
Provided is a lateral-electric-field mode active matrix liquid crystal display device in which an afterimage can be improved. The width of one pixel comb electrodeB of a plurality of pixel comb electrodesis larger than each of the widths of the other pixel comb electrodesand common comb electrodesand is equivalent to the width of a common shield electrodeB that covers an image signal wiring linevia a second insulating film. A display region is divided into two subregions by the wide pixel comb electrodeB. In each subregion, the number of pixel comb electrodesis equal to that of common comb electrodes. In addition, the width of the common shield electrodeB is equivalent to that of the wide pixel comb electrodeB, and the concentration of an electric field in the vicinity of each pixel comb electrode is reduced. Since structural symmetry is achieved, an electric potential distribution becomes symmetrical, and the asymmetry of the manners of emitting light between frames is reduced. As a result, the DC offset component of an image signal after flicker adjustment is reduced to improve an afterimage.
